AbstractSpace control missions require a high angular brightness and minimal jitter laser beam on the target. These characteristics are difficult to achieve on a real beam path through turbulent atmospheric conditions. MetroLaser’s proposal outlines an innovative approach in designing an Adaptive Laser System (ADLAS) based on a combination of linear and non-linear optical phase conjugation mirrors. This concept enables real time correction of the wavefront of a high-energy laser beam, resulting in a high Strehl ratio of the beam and significant increase of the energy density on the target. During Phase I, we performed a systematic analysis of the phase-conjugate, mirror-based laser, and proof-of-concept experiments to characterize key system parameters. In addition, the operational limits and constraints imposed by spatial aberrations on the beam path and the delivered energy requirements were identified and the projected performance envelope was estimated. A design trade-off analysis of the prototype architecture was also conducted. Results of Phase I confirmed feasibility of the proposed ADLAS concept. During Phase II, we plan to scale up the technology, build the brassboard, and perform its field demonstration.
